III. INSTALLATION
4. Expansion Cards
First read your expansion card documentation on any hardware and
software settings that may be required to setup your specific card.
NOTE: PCI Slot 5 has a MediaBus extension 2.0 (see page 18) which
allows the installation of a PCI card or a MediaBus card (optional
multifunctional card) but not both.
WARNING: Make sure that you unplug your power supply when
adding or removing expansion cards or other system components.
Failure to do so may cause severe damage to both your motherboard
and expansion cards.
Expansion Card Installation Procedure:
1. Read the documentation for your expansion card.
2. Set any necessary jumpers on your expansion card.
3. Remove your computer’s cover.
4. Remove the bracket on the slot you intend to use. Keep the bracket for
possible future use.
5. Carefully align the card’s connectors and press firmly.
6. Secure the card on the slot with the screw you removed in step 4.
7. Replace the computer’s cover.
8. Setup the BIOS if necessary.
9. Install the necessary software drivers for your expansion card.
Assigning IRQs for Expansion Cards
IMPORTANT: PCI Slots 4 & 5 share the same IRQ. If using PCI
cards on both slots 4 & 5, make sure that the drivers support "Share
IRQ" or that one card does not need an IRQ assignment. Conflicts will
arise on PCI Slots 4 & 5 that will make the system unstable.
Some expansion cards need to use an IRQ to operate. Generally an IRQ
must be exclusively assigned to one use. In an standard design there are 16
IRQs available but most of them are already in use by parts of the system
which leaves 6 free for expansion cards.
